Thanks,for the info.This header evac. setup you're talking about,from what I get from it is basically running your breathers down into your exhaust,where a factory setup would run into the air cleaner.Using an EGR valve would keep exhaust from coming up and into the valve cover ? If this is what you're saying,great info.! I guess what I'm lookin for is to keep the motor clean.An open breather does just that,lets the motor breath, and I'm looking for a way to keep the 'sweat' off the valve covers. How about just using a recovery tank? Something with its own remote breather and maybe a drain? Just a thought. Also,if going to the header route,do you still use a PCV valve? If not,with no vacuum being lost,you may have to lean out carb?
